¹British Phosphate
Commission (BPC), formed in 1920, controlled the
entire economy of Nauru, owned much of its
infrastructure and financed the official
administration, and thus they may be considered as
co-administrators of Nauru. The share of each of the
three powers in the operation was: United
Kingdom 42%, Australia 42%,
and New Zealand 16%. The
phosphate was only to be exported to the three
countries. In 1927, the BPC also formalized the
unofficial habit of paying a royalty to the Nauruans
that existed since the German period. The Commission
also controlled the phosphate mining on Christmas Island
and Ocean
(Banaba) Island.
